I/O Space
The I/O space on each IndustryPack is fixed at 128, 16-bit words (256 Bytes). (The I/O
space above 64 words is for future use.) This occupies a space of $100 Bytes. The six
IndustryPack I/O spaces are accessible at fixed offsets from the PCI-60A's Base
Address, as shown in Figures 2 and 3. Typically, IndustryPacks do not fully decode their
entire 64 long-word space. Some IndustryPacks support both word and byte accesses to
I/O space, while others require accesses to be byte-only or word-only. See each
IndustryPack's User Manual for details.
Caution: An IndustryPack may or may not fully decode its I/O space. Incomplete
decoding will often cause IndustryPack registers to appear in multiple places within the
64-word I/O space. IndustryPacks may have different read and write maps. Some
IndustryPacks require 16-bit accesses only. If an IndustryPack does not respond to an
invalid access, then the PCI-60A bus timer will respond [if enabled] and cause an
interrupt to alert the software.
